Help with finding a Story Line name.

[Thor God Of Thunder]

Basically I'm trying to think of that war between the registration and non registration. It had like cap and Ironman as apposing leaders. I cant remember anymore then that it's supposed to be kinda big thing I think lol. I think it was called Civil War or something...

[Geralt of Rivia]

Yeah you got it, thats Civil War and it wasnt all that good.
